Problem 1(5+5+5 pts ). You set up a communication channel between two medieval castles by letting a trained raven repeatedly carry a scroll from the sending castle to the receiving castle, 160 kilometers away. The raven flies at an average speed of 40km/h, and carries one scroll at a time. Each scroll contains 1.8 terabytes of data. Calculate the average data rate (in bps) of this channel when sending 1. 1.8 terabytes of data 2. 3.6 terabytes of data 3. an infinite supply of data (i.e., the raven works non-stop to eternity)
